Hi, it should be possible to use the relevant parts of Eclipse JDT without Eclipse. I have been parsing Java files using JDT in the past in a plain Java project, but I didn't try AST transformations, or compiling. But since the Maven compiler plugin can also switch to JDT-based compilations without having Eclipse installed, I guess it should not be a problem [1].
I think that JDT is probably one of the best options because I believe it gets updated rather quickly if there are changes to the Java language.
